As you say, a decision will only be made after a qualified engineering team are able to assess the damage. How one can even begin to analyse every potential hotspot for what is effectively internal granular restructuring on a vessel of that size is well below my pay scale.
Sometime after I left her, the Sir Galahad slipped beneath the waves off Stanley and watching the news at the time, it was devastating knowing the conditions under which so many perished. Another, the old Ark Royal eventually went for "razor blades", not so much dying as fading away.
A long time ago for me, but still brings back memories.
